A White House petition requesting that dentist Walter Palmer, who killed a prized lion in Zimbabwe, be extradited to the African nation to face justice should receive a response from the Obama administration.

The Empire State Building's famous light displays were used to draw attention endangered wildlife. Along with Cecil, whose death has sparked international outrage, a snow leopard, tigers, lemurs and various snakes, birds and sea creatures were projected onto the building.

The spectacle was staged to promote the documentary "Racing Extinction," a production of the Oceanic Preservation Society. Cecil wasn't included in the presentation originally but was added to honor him after he was killed, an Oceanic Preservation Society spokesperson said.

With the help of 40 projectors, images of the endangered wildlife moved across the south side of the building, dazzling viewers on the street and in nearby buildings. The moving images were a first for the Empire State Building, which is normally lit with colors and the occasional light show.

South Bronx cases double to 65 since Thursday

1977: Scientists at the Centers for Disease Control announce that they had sufficient laboratory evidence to implicate a previously unknown strain of bacteria as the cause of Legionnaire's Disease, now named Legionella pneumophila. An outbreak of the potentially fatal infectious disease in Philadelphia in 1976, largely among people attending a state convention of the American Legion, led to the name "Legionnaires' Disease." After the bacteria causing the illness was named, the name of the illness was changed to legionellosis.

The number of deaths in the New York City Legionnaires' disease outbreak is up to four.

Seventy-one cases of the flu-like disease have been reported since mid-July in the South Bronx, up from 31 on Thursday, the city Department of Health and Mental Hygiene said Sunday.

Legionnaires' disease is a respiratory bacterial infection usually spread through mist that comes from a water source, such as cooling towers, air conditioning or showers. It is not transmitted person to person. Symptoms of the disease include fever, chills and a cough.

Most people recover, but between 5% to 30% of those who get the disease die, according to the U.S. Centers for Disease Control and Prevention.

The four victims were all older adults with additional underlying medical problems, the city said. Fifty-five individuals are hospitalized.

"We are conducting a swift investigation to determine the source of the outbreak and prevent future cases. I urge anyone with symptoms to seek medical attention right away," Dr. Mary Bassett, commissioner of the health department, said on Thursday.

The department's probe includes testing water from potential sources in the area.

Five buildings in the outbreak cluster, including a hospital and a hotel, have so far tested positive for traces of the legionella bacteria. Environmental cleaning and taking any corrective measures needed has been completed in all five locations, the city said Sunday.

"The New York City water supply does not pose a risk, so people should continue to feel confident in drinking tap water to stay cool during this period of hot weather," said Bassett.

At a City Hall press conference Thursday afternoon, Mayor Bill de Blasio warned that anyone with symptoms should get tested, but he said that most New Yorkers are not at risk.

The city health department continues to employ disease detectives to investigate the source of the outbreak and is conducting outreach to vulnerable populations including the elderly and homeless. A town hall discussion between community members and city medical experts entitled "The Facts About Legionnaires Disease" is scheduled for Monday evening.

Bronx Borough President Ruben Diaz Jr. said on Friday that his office will push for legislation to create a citywide inspection system that would test building water infrastructure for the disease and others.

"The city must create a new inspection system for these systems, just as we inspect other critical systems such as elevators," Diaz said in statement.

An outbreak of the disease killed two people at a hotel in downtown Chicago in 2012.

An estimated 8,000 to 18,000 hospitalized cases of Legionaires' disease occurs each year in the United States. An outbreak of the disease in Philadelphia in 1976, largely among people attending a convention of the American Legion, led to its name.
